A steering wheel boss Hub Kit (sold separately) will be required unless you already have a modified steering wheel

WARNING: The replacement of the steering wheel on cars equipped with airbag systems will disable both the functioning of the airbag system of the driver and that of the front passenger or any other airbag fitted in the car. For cars equipped with airbag systems, these steering wheels are intended for racing use only. Failure to have a working airbag on a road use vehicle originally equipped with airbags, will fail an MOT. Do not attempt to install this kit yourself unless you have been properly trained in the installation and maintenance of car steering wheels. Do not attempt to install this kit without having previously read the instruction manual. Incorrect installation can lead to a steering wheel failure which can cause an accident resulting in serious personal injury or death.
CAUTION: Reduced steering wheel diameter will cause increased driver steering effort.
